banned unmodded console can at least still receive game updates from other switches, for what it's worth. you wont be able to get game dlc anymore, but if you have access to a modded console you can download updates online and install it on it, and share them to the banned unmodded console so you can at least get updates and bug fixes for games.
you might think why bother if you could just play the games directly on modded switch, but it's nice for if you prefer the Lite form factor for instance, or wanted to benefit from the better battery life and/or oled screen of the newer models compared to the v1. or maybe you dont actually own a modded switch, a friend does.
ofc this only works if the ticket for the update is genuine and hasn't been tampered with... which a certain popular installer intentionally does ;P
